Hello Tang Wang:
There are no plans to support KL17/27 with legacy Processor Expert drivers, only with KSDK.
There are some very useful tutorials about using KSDK with or without Processor Expert. I recommend you to start with those:
Writing my first KSDK1.2 Application in KDS3.0 - Hello World and Toggle LED with GPIO Interrupt
How to toggle LED in KDS 2.0 with KSDK 1.1.0 and Processor Expert
Video Link : 3195
And a series of videos for KDS:

In case you face any problems you can always search the community content or post your own questions and we will be glad to help.
Regards!,
Jorge Gonzalez
